Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS2806-4-F3 are qualified based on the following critical parameters:

• Number of Channels: 4 channels required
• Voltage - Isolation: 2500Vrms required
• Current Transfer Ratio (Min): 200% @ 1mA required
• Output Type: Darlington output required
• Voltage - Output (Max): 40V required
• Current - Output / Channel: 100mA required
• Operating Temperature Range: -55°C ~ 100°C required
• Mounting Type: Surface Mount required
• Package Configuration: 16-pin SOIC/SSOP package required

The following substitute parts maintain full parameter equivalence across all electrical and mechanical specifications:

PS2806-4-A (Renesas Electronics Corporation): Parametric equivalent with strip packaging. Maintains all isolation voltage, channel count, current transfer ratio, output voltage, and temperature specifications.

PS2806-4-F3-A (Renesas Electronics Corporation): Parametric equivalent with tape & reel packaging. Maintains all isolation voltage, channel count, current transfer ratio, output voltage, and temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

PS2806-4-A: This substitute offers parametric equivalence with ROHS3 compliance. Suitable for applications where RoHS compliance is required. The strip packaging format accommodates alternative procurement workflows. Product status of "Not For New Designs" indicates limited long-term availability.

PS2806-4-F3-A: This substitute provides full parametric equivalence with ROHS3 compliance and REACH Unaffected status. Tape & reel packaging supports standard production assembly processes. This option is preferred for applications requiring full regulatory compliance and long-term supply chain considerations.

Both substitutes maintain electrical and mechanical specifications identical to the original PS2806-4-F3, enabling direct functional replacement in 4-channel optoisolation applications with 2500Vrms isolation and Darlington output architecture.

Frequently Asked Questions (FAQ)

What determines if a part can substitute for the PS2806-4-F3?

Substitutes must maintain: 4-channel configuration, 2500Vrms isolation rating, 200% minimum current transfer ratio, Darlington output type, 40V maximum output voltage, 100mA per-channel output current, and full operating temperature range from -55°C to 100°C. Physical package configuration (16-SOIC) and surface mount mounting type must also remain constant.

Are PS2806-4-A and PS2806-4-F3-A directly compatible with PS2806-4-F3?

Yes. Both substitutes maintain identical electrical specifications and mechanical dimensions. The primary differences are packaging format (strip versus tape & reel), manufacturer designation (Renesas Electronics Corporation versus CEL), and regulatory compliance status.

What is the difference between PS2806-4-A and PS2806-4-F3-A?

Both are parametric equivalents with identical electrical and mechanical performance. The primary distinctions are: PS2806-4-A uses strip packaging, while PS2806-4-F3-A uses tape & reel packaging. PS2806-4-F3-A carries REACH Unaffected status, while PS2806-4-A carries REACH Affected status.

Why is the original PS2806-4-F3 marked as obsolete?

The manufacturer has discontinued this component. Renesas Electronics Corporation alternatives (PS2806-4-A and PS2806-4-F3-A) are available as direct replacements with improved regulatory compliance (ROHS3 vs. non-compliant status).

Which substitute should be selected for new production designs?

PS2806-4-F3-A is recommended for new designs. It provides ROHS3 compliance, REACH Unaffected status, tape & reel packaging for automated assembly, and maintains full parametric equivalence to the original part.
